" Application filed me 14, 1923. Serial No. 645,314.

To aZZ whom it may concern:

Be itlmown that I, HARRY Rs VAN DEVEN- run, a citizen of the United States, residing.

at .New York city, in the county of New .York and State of N. Y., have invented certain new and usefullmprovements in Combination Electric Batteries and Condensers,

lllyinvention relates to an electric battery and condenser such as is commonly used in connection with radio receiving sets.

When radio receiving set-s'are equipped with vacuum tubes, .it is customary to em ploy a battery of small dry cells commonly known as a B battery. It often occurs vthat these batteries are or after use become noisy, and it has been found that by bridging a condenser across the plurality of cells comprising the battery unit, that the noises will be wholly or partly eliminated.

The object of my invention is to provide a combination unit wherein the condenser is combined with a plurality of battery cells to form a unitary structure.

A further object is to provide a unitary structure comprising battery cells and a unit condenser in which the condenser can be readily removed and replaced.

Another object is to provide a unitary structure comprising a plurality of battery cells and'a condenser the latter having a terminal adapted to be placed in contact with the terminals of a plurality of the cells.

Figure'l is a view looking down upon a. unitary structure embodying my invention. Figure- 2.is a view of the unitary structure having the end broken away to show how the condensers may be positioned therein.

Figure 3 is a circuit diagram of the combi-' nation of battery cells and condenser.

For the sake of illustration, I will describe my-invention as arranged for an ordinary B battery commonly'used in connection with radio receiving sets. Such a battery commonly consists of a plurality of small drycells usually connected in series, placed within a suitable'container, the outer casing of whichI have designated by the numeral 1.. As the construction and arrangement of the dry cells arewell known and may be varied with wide limits, I do not showor dcscribe the same, it being sufficient to state that the dry cells are suitably a ugg d with- "in the container 1 and electrically ctnnected in any desired manner, it being understood that the container 1 is filled with wax or other compound from which progcets the negative terminal 2 and, usually, a plurality of positive terminals 3, 4, 5, 6 and? wl'rereby various voltages can be taken oil.

Iloused in the casing l with the dry cells so as to form a unitary structure, I provide a suitable condenser indicated. by; the nu lneral 8. This condenser may be of any suit-- able form and construction, and, as many types are known, I do not describe the same 1n detail. v

did

The condenser may be positioned within the casing 1 by imbedding it in the wa t or other compound 12"wl uch surrounds and secures the dry cells in place. The condenser is provided with two terminal leads 9 and 10. The lead 9' may be permanently COl'lr nected to the terminal 2 (underneath the wax) or it may be removably connected thereto.

The terminallO is brought out above the wax and left long enough to conmeet to any one of the positive terminals wax may be taken out of 11 and the condenser removed, and the rest of the unit thrown away. i

It will be observed that the battery cells and the container 1 form no part of the condenser structure. This enables the condenser to be manufactured and tested connplete and then assembled with the battery cells-to formv the complete unit as-described,
